Application

  • Use to fire proof ventilation ducts which penetrate fire rated constructions such as fire compartments and fire walls, presenting the passage of fire and smoke.
  • The product seals against penetration of fire and smoke, surrounding and inside the ventilation duct.
  • Applicable for drywalls, masonry and concrete walls, timber walls, concrete floors and timber floors.
  • The aperture surrounding the dampers are fire sealed with Protecta fire stopping products.

Description

A fire damper product consist of steel casing and contains horizontal steel blades, treated with a technically advanced heat expanding graphite which closes off the whole damper in a fire. The aperture surrounding the dampers are fire sealed with Protecta fire stopping products.


The damper can be installed in the fire seal and the ventilation ducting attached, or the damper can be connected to the ducting and then fire sealed.


The aperture where the ducts pass through can include one or multiple ventilation ducts. One can also pass through other technical services such as cables, cable trays and pipes within the same aperture.


Features and benefits:

  • Maintenance free and no electrical connection necessary.
  • An aperture can include several dampers and in addition, technical services such as cables, cable trays and pipes.
  • Closes in the area where the fire is located (but not elsewhere), allowing the ventilation system to extract smoke from areas that are not on fire.
  • Keeps the temperature in the duct network lower than 120°C, protecting fans and sensitive units in the system.
  • Insulation of ducts is not necessary.
  • Service life of more than 50 years; the damper will last the same life cycle as the ventilation system.
  • The dampers are designed to fit standard ducting equipment, enabling the ducting system installer to easily fit the dampers.
  • The dampers are attached to the inside of the ducts, giving the benefit of space saving.
  • The damper cab be attached to a vent on one side.
  • Interior climate, installed: Z², Relative air moisture up to 85% and temperatures between five and 40 °C.
  • Trigger-temperature in fire: 100°C.
  • Full closure temperature: 160°C.
  • Time to full closure: From 50 seconds to two minutes.
  • Expansion rate graphite: 15.5 to 17.
  • Density graphite: 2.6 kg/L.


The 'close in and pull out' principle:

A combined ‘close in and pull out’ solution is one that prevents the spread of fire by closing off the fire inside the fire compartment, using the ventilation system outside the area of the fire to pull out any smoke that filters out through the fire compartments constructions.


Dust formation and general maintenance:

Tests conducted on Protecta® FR Damper to determine dust formation inside the damper, has shown that dust does not collect inside the damper, and no more than in any other components in the ventilation system. The dust tends to be blown through the dampers as long as the ventilation system is in constant operation and installed in normal indoor environments (Z2).
